Description

接口切换控制方法及使用该方法的便携终端和便携移动设备 技术领域 本申请涉及通信技术领域， 特别涉及一种接口切换控制方法、 便携终端、 便携移动设 备及输入设备。 背景技术 混合系统架构的便携终端， 是在现有仅有一个系统的 PC (Personal Computer, 个人 计算机） 基础上， 嵌入其它至少一个系统的 PC。 不同系统之间可以融合工作， 发挥各自优 势。 现有常见的混合系统架构的便携终端通常集成了一个主系统 （例如， X86 系统） 和一 个从系统 （例如， ARM系统）， 主系统和从系统之间可以共用共享设备， 如键盘、 网卡、 显 示屏、 存储设备、 Audio 等。 以笔记本电脑为例， 通常从系统集成在显示屏所在的从设备 上， 而主系统集成在键盘所在的主设备上， 主设备和从设备之间可以组合在一起工作， 也 可以各自独立工作， 当独立工作时， 显示屏由从设备使用， 当组合在一起工作时， 显示屏 可以由主设备或者从设备任意一方使用。  TECHNICAL FIELD The present application relates to the field of communications technologies, and in particular, to an interface switching control method, a portable terminal, a portable mobile device, and an input device. BACKGROUND OF THE INVENTION A portable terminal of a hybrid system architecture is a PC embedded in at least one other system based on a PC (Personal Computer) having only one system. Different systems can work together to take advantage of their respective strengths. Portable terminals of the existing common hybrid system architecture usually integrate a main system (for example, an X86 system) and a slave system (for example, an ARM system), and a shared device such as a keyboard, a network card, or the like can be shared between the master system and the slave system. Display, storage device, Audio, etc. Taking a notebook computer as an example, the system is usually integrated on the slave device where the display screen is located, and the master system is integrated on the master device where the keyboard is located. The master device and the slave device can work together in combination, or can work independently. When working independently, the display is used by the slave device. When working together in combination, the display can be used by either the master device or the slave device.
在对现有混合架构的便携终端进行研究的过程中发现， 现有主设备和从设备在共用共 享设备时， 需要统一接口总线的设置， 即每个设备都采用相同的接口总线挂载共享设备。 因此， 为了兼容其中一个设备的所有接口， 必须要对另一个设备的接口进行扩展， 以保持 二者的一致性。 但是， 对于混合系统的便携终端来说， 根据各个设备的系统性能需求不同， ARM系统要求接口能够快速响应、 功耗低， 而 X86系统要求接口总线通用， 以减少驱动挂 载的数量， 因此采用统一接口的方式将会降低便携终端的系统性能， 无法满足各个系统的 需求。  In the process of researching the portable terminal of the existing hybrid architecture, it is found that the existing master device and the slave device need to unify the interface bus when sharing the shared device, that is, each device uses the same interface bus to mount the shared device. . Therefore, in order to be compatible with all interfaces of one of the devices, the interface of the other device must be extended to maintain consistency between the two. However, for portable terminals of hybrid systems, depending on the system performance requirements of each device, the ARM system requires the interface to respond quickly and consumes low power, while the X86 system requires the interface bus to be common to reduce the number of drive mounts. The way to unify the interface will reduce the system performance of the portable terminal and will not meet the needs of each system.

由以上本申请实施例提供的技术方案可见， 本申请中的便携终端包括第一设备和第二 设备， 其中第一设备通过第一接口与共享设备连接， 第二设备通过第二接口与共享设备连 接， 便携终端具有所述第一设备和第二设备连接的第一状态， 以及第一设备和所述第二设 备分离的第二状态， 检测便携终端所处的状态， 产生一检测结果， 当检测结果表示便携终 端处于所述第一状态时， 控制第一接口处于使能状态， 以及控制第二接口处于非使能状态， 以使第一设备响应共享设备输入的信息。 以 X86系统、 ARM为例， 现有技术中对于混合系 统的便携终端来说， 根据各个设备的系统性能需求不同， ARM系统要求接口能够快速响应、 功耗低， 而 X86系统要求接口总线通用， 以减少驱动挂载的数量， 因此采用统一接口的方 式将会降低便携终端的系统性能， 无法满足各个系统的需求。 例如， 若统一使用 USB作为 共享设备（如触摸屏）的接口， 虽然满足了 X86系统可以减少驱动挂载的数目， 但是在 ARM 系统使用的时候， 功耗较大且从休眠唤醒的时候由于 USB驱动要重新挂载， 必然使系统响 应变慢。 与现有技术相比， 本申请实施例为共享设备提供了至少两个接口， 并且实现了对 共享设备的接口的实时切换控制， 优化了混合系统架构的便携终端的接口控制； 通过根据 便携终端所处状态的不同， 将各个设备所需使用的接口进行使能， 从而满足了不同设备的 系统性能， 降低了系统功耗。 附图说明 图 1为本申请接口切换控制方法的第一实施例流程图； The portable device provided in the present application includes the first device and the second device, where the first device is connected to the shared device through the first interface, and the second device is connected to the shared device through the second interface. Connecting, the portable terminal has a first state in which the first device and the second device are connected, and a second state in which the first device and the second device are separated, detecting a state in which the portable terminal is located, generating a detection result, when The detection result indicates that when the portable terminal is in the first state, the first interface is controlled to be in an enabled state, and the second interface is controlled to be in a non-enabled state, so that the first device responds to the information input by the shared device. Taking the X86 system and ARM as an example, in the prior art, for the portable terminal of the hybrid system, according to the system performance requirements of each device, the ARM system requires the interface to respond quickly and the power consumption is low, and the X86 system requires the interface bus to be universal. In order to reduce the number of drive mounts, the use of a unified interface will reduce the system performance of the portable terminal and cannot meet the requirements of each system. For example, if USB is used as the interface of a shared device (such as a touch screen), although the X86 system can be used to reduce the number of drive mounts, when the ARM system is used, the power consumption is large and wake up from sleep due to the USB drive. To remount, the system response will be slowed down. Compared with the prior art, the embodiment of the present application provides at least two interfaces for the shared device, and implements real-time switching control of the interface of the shared device, and optimizes interface control of the portable terminal of the hybrid system architecture; The state of the portable terminal is different, and the interfaces required for each device are enabled, thereby satisfying the system performance of different devices and reducing the system power consumption.

为了使本技术领域的人员更好地理解本申请实施例中的技术方案， 并使本申请实施例 的上述目的、 特征和优点能够更加明显易懂， 下面结合附图对本申请实施例中技术方案作 进一步详细的说明。  The above-mentioned objects, features, and advantages of the embodiments of the present application can be more clearly understood and understood by those skilled in the art. Give further details.
本申请实施例中的接口切换控制方法应用在包含第一设备和第二设备的便携终端中， 其中， 第一设备通过第一接口与共享设备连接， 所述第二设备通过第二接口与所述共享设 备连接， 所述便携终端具有所述第一设备和第二设备连接的第一状态， 以及所述第一设备 和所述第二设备分离的第二状态。 其中， 本实施例中的共享设备可以为一输入设备， 更进 一步， 该输入设备可以为一触摸输入设备， 例如， 触摸屏。 共享设备可以与第一设备集成 一体， 也可以与第二设备集成一体。  The interface switching control method in the embodiment of the present application is applied to a portable terminal that includes a first device and a second device, where the first device is connected to the shared device by using the first interface, and the second device is connected to the shared device by using the second interface. A shared device connection, the portable terminal having a first state in which the first device and the second device are connected, and a second state in which the first device and the second device are separated. The shared device in this embodiment may be an input device. Further, the input device may be a touch input device, for example, a touch screen. The shared device can be integrated with the first device or integrated with the second device.
例如， 便携终端的第一设备可以具体为运行 X86系统的主设备， 第二设备可以具体为 运行 ARM系统的从设备， 第一接口可以具体为 USB接口， 第二接口可以具体为 UART接口。 假设共享输入设备为与从设备集成一体的触摸屏， 则当主设备和从设备处于第一状态， 即 X86系统和 ARM系统组成混合系统进行工作时， 可以仅使能 USB接口， 以使主设备上的 X86 系统可以响应触摸屏的输入信息， 当主设备和从设备处于第二状态， 即 X86系统和 ARM系 统分别单独使用时， 则可以仅使能 UART接口， 以使从设备的 ARM系统可以响应触摸屏的输 入信息。 通过在便携终端处于不同的连接状态时， 使能不同的接口， 以适应不同系统的需 求， 节约系统功耗。 For example, the first device of the portable terminal may be a master device running the X86 system, and the second device may be a slave device running the ARM system. The first interface may be specifically a USB interface, and the second interface may be specifically a UART interface. Assuming that the shared input device is a touch screen integrated with the slave device, when the master device and the slave device are in the first state, that is, the X86 system and the ARM system are combined to work, the USB interface can be enabled only to enable the master device. X86 The system can respond to the input information of the touch screen. When the master device and the slave device are in the second state, that is, the X86 system and the ARM system are respectively used separately, the UART interface can be enabled only, so that the ARM system of the slave device can respond to the input information of the touch screen. . By enabling different interfaces when the portable terminals are in different connection states, to meet the needs of different systems, system power consumption is saved.
所述第一接口符合第一设备的系统要求 /规范。所述第二接口符合第二设备的系统要求 The first interface conforms to system requirements/specifications of the first device. The second interface meets the system requirements of the second device
/规范。更进一步，所述第二接口与所述第一接口不同。例如，运行了 X86系统的第一设备， USB接口为其通用接口， 且系统已自带驱动。 因此， 触摸屏以 USB的方式接入系统。 无须 额外挂载驱动。 另外， 运行了 ARM系统的第二设备， 使用 UART作为 ARM系统的接口， 功耗 较 USB低， 且 UART在 ARM系统下无须额外挂载驱动， 因此触摸屏响应速度比 USB快。 /specification. Further, the second interface is different from the first interface. For example, the first device running the X86 system, the USB interface is its common interface, and the system has its own driver. Therefore, the touch screen is connected to the system in USB mode. No additional mounting drivers are required. In addition, the second device running the ARM system uses the UART as the interface of the ARM system, the power consumption is lower than that of the USB, and the UART does not need to be additionally mounted on the ARM system, so the touch screen responds faster than the USB.
参见图 1， 为本申请接口切换控制方法的第一实施例流程图， 其中第一设备为主设备， 第二设备为从设备： Referring to FIG. 1, a flowchart of a first embodiment of an interface switching control method according to the present application, where a first device is a master device, and a second device is a slave device:
步骤 101 : 检测便携终端所处的状态， 产生一检测结果。  Step 101: Detecting a state in which the portable terminal is located, and generating a detection result.
以共享设备与从设备集成一体为例， 在从设备和主设备上分别具有连接端口， 通过连 接端口可以使主设备和从设备在物理上实现连接或者断开。 本实施例中， 由从设备根据连 接端口的连接情况检测便携终端是处于主设备和从设备相连的第一状态， 还是主设备与从 设备断开的第二状态。  For example, the integrated device and the slave device are integrated, and the slave device and the master device respectively have a connection port, and the master device and the slave device can be physically connected or disconnected through the connection port. In this embodiment, the slave device detects whether the portable terminal is in the first state in which the master device and the slave device are connected according to the connection condition of the connection port, or is the second state in which the master device is disconnected from the slave device.
其中， 共享设备可以分别通过从设备内的控制单元与设置在从设备上的第一接口和第 二接口相连， 或者也可以将第一接口和第二接口设置在共享设备上。 主设备可以通过第一 接口与共享设备连接， 从设备可以通过第二接口与共享设备连接。  The shared device may be connected to the first interface and the second interface disposed on the slave device by using a control unit in the slave device, or may be configured on the shared device by using the first interface and the second interface. The master device can be connected to the shared device through the first interface, and the slave device can be connected to the shared device through the second interface.
步骤 102 : 当检测结果表示便携终端处于第一状态时， 控制第一接口处于使能状态， 以及控制第二接口处于非使能状态， 以使第一设备响应共享设备输入的信息。  Step 102: When the detection result indicates that the portable terminal is in the first state, control the first interface to be in an enabled state, and control the second interface to be in a non-enabled state, so that the first device responds to the information input by the shared device.
本申请实施例中， 当检测结果表示便携终端处于主设备和从设备相连的第一状态时， 由从设备内的控制单元控制第一接口使能， 以及控制第二接口非使能， 此时主设备可以通 过第一接口响应共享设备输入的信息。  In the embodiment of the present application, when the detection result indicates that the portable terminal is in the first state in which the master device and the slave device are connected, the first interface is enabled by the control unit in the slave device, and the second interface is disabled. The master device can respond to the information input by the shared device through the first interface.
参见图 2， 为本申请接口切换控制方法的第二实施例流程图， 其中第一设备为主设备， 第二设备为从设备： 2 is a flowchart of a second embodiment of an interface switching control method according to the present application, where a first device is a master device, and a second device is a slave device:
步骤 201 : 检测便携终端所处的状态。 仍然以共享设备与从设备集成一体为例， 在从设备和主设备上分别具有连接端口， 通 过连接端口可以使主设备和从设备在物理上实现连接或者断开。 本实施例中， 由从设备根 据连接端口的连接情况检测便携终端是处于主设备和从设备相连的第一状态， 还是主设备 与从设备断开的第二状态。 具体的， 可以通过电平信号的高低指示进行状态检测， 在接收 到接口连接器传输的电平信号时， 如果电平信号为高电平信号， 则确定便携终端处于第一 状态， 如果电平信号为低电平信号， 则确定便携终端处于第二状态。 Step 201: Detect a state in which the portable terminal is located. For example, the shared device and the slave device are integrated as an example, and the slave device and the master device respectively have a connection port, and the master device and the slave device can be physically connected or disconnected through the connection port. In this embodiment, the slave device detects whether the portable terminal is in the first state in which the master device and the slave device are connected according to the connection condition of the connection port, or is the second state in which the master device is disconnected from the slave device. Specifically, the state detection may be performed by the level indication of the level signal. When the level signal transmitted by the interface connector is received, if the level signal is a high level signal, it is determined that the portable terminal is in the first state, if the level When the signal is a low level signal, it is determined that the portable terminal is in the second state.
例如， 共享设备可以分别通过从设备内的控制单元与设置在从设备上的第一接口和第 二接口相连， 或者也可以将第一接口和第二接口设置在共享设备上。 主设备可以通过第一 接口与共享设备连接， 从设备可以通过第二接口与共享设备连接。  For example, the shared device may be connected to the first interface and the second interface disposed on the slave device through a control unit in the slave device, respectively, or the first interface and the second interface may also be disposed on the shared device. The master device can be connected to the shared device through the first interface, and the slave device can be connected to the shared device through the second interface.
步骤 202 : 根据检测结果判断便携终端所处的状态， 若为第一状态， 则执行步骤 203 ; 若为第二状态， 则执行步骤 204。  Step 202: Determine, according to the detection result, a state in which the portable terminal is located. If it is the first state, step 203 is performed; if it is the second state, step 204 is performed.
步骤 203 : 控制所述第一接口处于使能状态， 以及控制所述第二接口处于非使能状态， 以使所述第一设备响应所述共享设备输入的信息， 结束当前流程。  Step 203: Control the first interface to be in an enabled state, and control the second interface to be in a non-enabled state, so that the first device responds to the information input by the shared device, and ends the current process.
当检测结果表示便携终端处于主设备和从设备相连的第一状态时， 由从设备内的控制 单元控制第一接口使能， 以及控制第二接口非使能， 此时主设备可以通过第一接口响应共 享设备输入的信息。  When the detection result indicates that the portable terminal is in the first state in which the master device and the slave device are connected, the first interface is enabled by the control unit in the slave device, and the second interface is disabled, and the master device can pass the first The interface responds to information entered by the shared device.
步骤 204: 控制所述第二接口处于使能状态， 以使所述第二设备响应所述共享设备输 入的信息。  Step 204: Control the second interface to be in an enabled state, so that the second device responds to information input by the shared device.
当检测结果表示便携终端处于主设备和从设备断开的第二状态时， 此时与从设备集成 为一体的共享设备可以在从设备系统控制下工作， 因此由从设备内的控制单元控制第二接 口使能， 从设备可以通过第二接口响应共享设备输入的信息。  When the detection result indicates that the portable terminal is in the second state in which the master device and the slave device are disconnected, the shared device integrated with the slave device at this time can operate under the control of the slave device system, and thus is controlled by the control unit in the slave device. The second interface is enabled, and the slave device can respond to the information input by the shared device through the second interface.
此时， 由于主设备和从设备在物理状态上已经断开， 因此无论第一接口是否使能， 主 设备都无法通过第一接口响应共享设备的输入信息。 但是， 为了进一步节省第一接口的功 耗， 从设备的控制单元可以在控制第二接口处于使能状态的同时， 控制第一接口处于非使 能状态。  At this time, since the master device and the slave device are disconnected in the physical state, the master device cannot respond to the input information of the shared device through the first interface regardless of whether the first interface is enabled or not. However, in order to further save the power consumption of the first interface, the control unit of the slave device can control the first interface to be in a non-enabled state while controlling the second interface to be in an enabled state.
参见图 3， 为应用上述方法实施例进行接口切换控制的一种便携终端从设备内的检测 控制模块的结构示意图， 该便携终端的触摸屏与从设备集成为一体， 由从设备内的控制单 元 EC对接口使能进行控制。 例如， 假设运行 X86系统的主设备称为 PE， 运行 ARM操作系统的从设备称为 SE。 图 3 中示出了触摸屏检测控制模块中的控制单元 MCU, 该 MCU与接口连接器 CONNECTOR相连， 两个接口 USB和 UART分别与 CONNECTOR和 MCU相连， 触摸屏检测控制模块通过 CONNECTOR 对外与 ARM系统从设备 SE相连。 EC检测得到的检测信息可以通过 CONNECTOR传输给 MCU, 并且当两个接口 USB和 UART中的任意一个使能时， T0UCHPANEL传输的输入信息可以通过 使能的接口与 CONNECTOR的连接供给 PE或者 SE响应。 Referring to FIG. 3, a schematic structural diagram of a detection control module in a portable terminal slave device for performing interface switching control using the above method embodiment, the touch screen of the portable terminal is integrated with the slave device, and the control unit EC in the slave device is integrated. Control the interface enable. For example, suppose a master device running an X86 system is called a PE, and a slave device running an ARM operating system is called an SE. Figure 3 shows the control unit MCU in the touch screen detection control module. The MCU is connected to the interface connector CONNECTOR. The two interfaces USB and UART are connected to the CONNECTOR and MCU respectively. The touch screen detection control module communicates with the ARM system slave device through CONNECTOR. SE is connected. The detection information obtained by the EC detection can be transmitted to the MCU through CONNECTOR, and when either of the two interfaces USB and UART is enabled, the input information transmitted by T0UCHPANEL can be supplied to the PE or SE response through the connection of the enabled interface with the CONNECTOR.
具体来说， 当 SE插入到 PE时， SE和 PE组成混合系统工作：  Specifically, when SE is inserted into the PE, SE and PE work in a hybrid system:
SE内的 EC检测到有 PE接入， 则将电平信号 TP— SEU拉高， 生成高电平信号， MCU通 过触摸屏检测控制模块 CONNECTOR检测到 TP— SEU为高电平信号， 于是将 USB接口 ENABLE (使能）， 并将 UART接口 DISABLE (非使能）。此时，触摸屏 T0UCHPANEL的对外接口为 USB, 即由 PE通过该 USB接口响应触摸屏的输入信息。 由于 PE上运行 X86系统， 而 USB接口为 通用接口， 且 X86系统已自带 USB接口的驱动， 因此， 无须再额外挂载驱动。  When the EC in the SE detects PE access, the level signal TP_SEU is pulled high to generate a high level signal, and the MCU detects the TP_SEU as a high level signal through the touch screen detection control module CONNECTOR, and thus the USB interface ENABLE (enable), and the UART interface DISABLE (not enabled). At this time, the external interface of the touch screen T0UCHPANEL is USB, that is, the PE responds to the input information of the touch screen through the USB interface. Since the X86 system runs on the PE, and the USB interface is a universal interface, and the X86 system has its own USB interface driver, there is no need to additionally mount the driver.
当 SE从 PE内拔出时， SE和 PE分别独立工作：  When the SE is pulled out of the PE, SE and PE work independently:
SE内的 EC检测到 PE拔出， 则将电平信号 TP— SEU拉低， 生成低电平信号， MCU通过 触摸屏检测控制模块 CONNECTOR检测到 TP— SEU为低电平信号， 于是将 UART接口 ENABLE (使能）， 并将 USB接口 DISABLE (非使能）。此时，触摸屏 T0UCHPANEL的对外接口为 UART, 即由 SE通过该 UART接口响应触摸屏的输入信息。 由于 SE上运行 ARM系统， 使用 UART作 为 ARM系统的接口， 与使用 USB作为 ARM系统的接口相比， 可以降低功耗， 并且 UART在 ARM系统下无须额外挂载驱动， 因此响应速度也比 USB快。  When the EC in the SE detects the PE pull-out, the level signal TP_SEU is pulled low to generate a low-level signal, and the MCU detects the TP_SEU as a low-level signal through the touch screen detection control module CONNECTOR, so the UART interface ENABLE (Enable), and the USB interface DISABLE (not enabled). At this time, the external interface of the touch screen T0UCHPANEL is a UART, that is, the SE responds to the input information of the touch screen through the UART interface. Since the ARM system runs on the SE, the UART is used as the interface of the ARM system. Compared with the interface using the USB as the ARM system, the power consumption can be reduced, and the UART does not need to be additionally mounted in the ARM system, so the response speed is faster than the USB. .
进一步， 参见图 4A， 示出了应用本申请实施例进行接口切换控制的一个从设备的整体 架构示意图； 参见图 4B， 示出了应用本申请实施例进行接口切换控制的一个主设备的整体 架构示意图。 Further, referring to FIG. 4A, a schematic diagram of an overall architecture of a slave device applying interface switching control according to an embodiment of the present application is shown. Referring to FIG. 4B, an overall architecture of a master device applying interface switching control according to an embodiment of the present application is shown. schematic diagram.
结合图 4A和图 4B可知， 其中 BASEDocking为从设备的连接端口， SLATEDocking为主 设备的连接端口。主设备和从设备通过上述 BASEDocking和 SLATEDocking实现物理连接和 物理断开。  As shown in FIG. 4A and FIG. 4B, where the Shockocking is the connection port of the slave device, SLATEDocking is the connection port of the master device. The master device and the slave device are physically connected and physically disconnected by the above-mentioned BASEDocking and SLATEDocking.
在图 4A所示的从设备中， 多触摸模组 Multi-Touch与显示屏 LCD相连， Multi-Touch 与控制单元 MCU相连， Multi-Touch内包含接口连接器。根据 BASEDocking和 SLATEDocking 之间的连接状态， 若 BASEDocking和 SLATEDocking连接， 则 MCU通过 Multi-Touch内的接 口连接器检测到 TP— SEU为高电平信号， 此时 MCU控制 USB接口使能， UART接口非使能， 则主设备可以通过 USB接口响应显示屏 LCD的输入信息， 由于 UART接口非使能， 因此从设 备无法通过该 UART接口响应显示屏 LCD的输入信息； 若 BASEDocking和 SLATEDocking断 开， 则 MCU通过 Mult i-Touch内的接口连接器检测到 TP— SEU为低电平信号， 此时 MCU控 制 USB接口非使能， UART接口使能， 则从设备可以通过 UART接口响应显示屏 LCD的输入 信息， 而无论 USB接口是否使能， 由于主设备与从设备之间已经物理断开， 因此主设备都 无法通过 USB接口响应 LCD显示屏输入的信息， 但是为了节约系统功耗， 可以由 MCU控制 USB接口非使能。 In the slave device shown in FIG. 4A, the multi-touch module Multi-Touch is connected to the display LCD, the Multi-Touch is connected to the control unit MCU, and the Multi-Touch includes an interface connector. According to the connection status between BASEDocking and SLATEDocking, if BASEDocking and SLATEDocking are connected, the MCU is connected through the Multi-Touch. The port connector detects that TP_SEU is a high level signal. At this time, the MCU controls the USB interface to be enabled. If the UART interface is not enabled, the master device can respond to the input information of the display LCD through the USB interface, because the UART interface is not enabled. Therefore, the slave device cannot respond to the input information of the display LCD through the UART interface; if the BASEDocking and SLATEDocking are disconnected, the MCU detects that the TP_SEU is a low level signal through the interface connector in the Mult i-Touch, at this time, the MCU When the control USB interface is disabled and the UART interface is enabled, the slave device can respond to the input information of the display LCD through the UART interface, regardless of whether the USB interface is enabled or not, because the master device and the slave device are physically disconnected, so the master The device cannot respond to the information input by the LCD display through the USB interface, but in order to save system power consumption, the MCU can control the USB interface to be disabled.
